Features: This book is a specialized monograph on modern mobile communication systems and related technologies, consisting of two parts. Part 1 provides a detailed introduction to the fundamental concepts, theories, and technologies of mobile wireless communication systems, including transmission, signal processing, network planning, security, and mobility management. Part 2 primarily introduces various terrestrial mobile wireless communication systems and their related standards, such as TETRA, DECT, PACS, PHS, GSM, IS-95, PDC, CDPD, IEEE802.1, and HiperLAN. The content is rich, systematic, and presented in an accessible manner, making it suitable for engineers and technicians involved in mobile communication design and implementation, as well as for teaching purposes in higher education institutions.
In 1897, Guglielmo Marconi successfully conducted the first wireless communication between two moving ships in the English Channel. Since then, research and development in wireless communication have been driven with great enthusiasm. The demand for wireless communication, particularly mobile communication, has grown dramatically, and people are eagerly anticipating the arrival of the ideal personal communication era of "5W" (where anyone, anywhere, can communicate with anyone for any purpose—voice, data, and images).
Although mobile wireless communication has evolved over more than a century, the most remarkable period of rapid development occurred in the two decades following the 20th century. The swift progress in mobile communication during this time can be attributed to the rapid advancement of microelectronics technology and the continuous refinement of innovative cellular technology (frequency reuse and handover). Mobile communication has become one of the most dynamic and vibrant sectors in the modern IT industry, with an average annual growth rate of over 30% worldwide, far exceeding the annual GDP growth rate. It is predicted that this growth trend will persist in the coming decades. As a result, mobile communication has not only brought great convenience to human society but has also created immense wealth.
The Internet has emerged as another emerging industry in the past decade. Its development has injected new vitality into mobile communication, expanding its potential: wireless mobile office, wireless mobile banking, wireless mobile education. In summary, wireless Internet is quietly entering every corner of human society.
With the seamless integration of mobile communication and the Internet, what will the world become? No one can predict, and the business opportunities it will bring are also beyond estimation. The modern saying "It's not hard to achieve what you can imagine, but it's hard to imagine what you can't achieve" perfectly captures the challenges and opportunities wireless mobile Internet will present.
It is predicted that by 2005, the number of users on mobile communication networks will exceed 800 million, while the number of Internet users will surpass 700 million. Such a vast potential market has led the communication industry to focus on this direction in recent years, giving rise to new concepts and terms like GPRS, 3G, and WAP.
With the advent of 3G (Third-Generation Mobile Communication), mobile communication and the Internet will achieve perfect synergy, bringing the era of true 5W personal communication closer to reality. Let us eagerly await this moment!
This book is a specialized monograph on modern mobile communication systems and related technologies, divided into two parts: Part 1 (Chapters 1–8) primarily discusses the fundamental technologies and concepts of mobile wireless communication; Part 2 (Chapters 9–14) introduces several of the most important existing mobile communication systems. Chapter 1 serves as an overview, introducing the history of mobile communication and providing a brief overview of some of the standardization organizations and regulatory bodies related to mobile communication worldwide. Chapter 2 briefly describes the different characteristics of the mobile wireless environment and their impact on mobile wireless links, as well as introducing several important models used for signal propagation prediction. Chapter 3 discusses multiple access techniques and how bandwidth can be shared among multiple users, while also introducing random access protocols. Chapter 4 revisits the differences between wireless modems and discusses how they are used to overcome various challenges posed by wireless transmission. Chapter 5 addresses security, one of the most important issues related to the use of radio resources. It primarily focuses on how systems protect against unauthorized user intrusion and eavesdropping, fostering trust in wireless communication. Chapter 6 discusses the concept of cellular, which enables frequency reuse and allows for coverage of virtually unlimited areas, serving an almost unlimited number of users. This chapter provides a detailed introduction to the fundamental concepts of cellular systems and discusses technologies used to enhance the inherent capacity of cellular systems, such as power control and frequency hopping. Chapter 7 focuses on the design of cellular systems, including engineering implementation and cellular design, covering each step in the process. Chapter 8 provides a detailed introduction to mobility management functions, such as handover and location management (also known as slow mobility), along with their related technologies.
Part 2 primarily introduces terrestrial wireless communication systems, discussing five types of systems: professional wireless communication systems, cordless systems, paging systems, cellular networks, and data transmission systems. This part also introduces several major digital system standards, including TETRA, DECT, PHS, ERMES, GSM, IS-95, PDC, IEEE802.11, HIPERLAN, MOBITEX, and CDPD. Chapter 9 introduces the ancient mobile telecommunication system, known as Personal Mobile Radio (PMR). Chapter 10 focuses on cordless telephone systems, with an additional discussion on fixed wireless access systems, or Wireless Local Loop (WLL). Chapter 11 introduces paging systems, also known as one-way information broadcasting. Chapter 12 provides a brief introduction to several widely used cellular systems. Since related issues concerning system management were discussed in Part 1, this chapter is limited to introducing the main features of these systems, such as system architecture and wireless interfaces. Chapter 13 focuses on wide-area data transmission systems and wireless local networks.
As a comprehensive monograph on modern mobile communication systems and related technologies, this book is rich in content and highly systematic. It is illustrated with diagrams and presented in an accessible, clear, and easy-to-understand manner. While emphasizing the fundamental concepts and technologies of mobile communication, the book also provides in-depth coverage of the standards and engineering design methods for various mobile communication systems. Thus, it functions as a practical reference manual, offering significant value and guidance for engineers and technicians involved in mobile communication system design and implementation.
Although primarily written for engineers and technicians, Part 1 of this book introduces the fundamental concepts, theories, and technologies of mobile communication in a concise, clear, and easy-to-understand manner, making it suitable for students and faculty in relevant higher education fields. Part 2, which provides detailed introductions to nearly all current terrestrial mobile communication systems, will help students bridge theory with practice, deepen their understanding of actual mobile communication systems, and systematically master the knowledge they have learned, laying a solid foundation for future careers. Therefore, this book is not only an excellent reference for engineers and technicians but also a valuable teaching resource for relevant higher education programs.
